The Standard Model of Particle Physics
This is a set of lecture notes on the Standard Model of Particle Physics. It doesn't actually mention the Standard Model itself all that much, but goes into various topics in particle physics which extend understanding of the field. It is given in the 3rd year so should be reasonably accessible to anyone who has done a bit of quantum mechanics and some special relativity.
